• Summary: Learn about 有害垃圾 (yǒuhài lājī), the official Chinese term for “hazardous waste” or “harmful trash.” This term is a crucial piece of daily vocabulary for anyone living in or traveling to China, due to the nationwide implementation of strict waste sorting laws. This guide breaks down its meaning, cultural significance, and practical usage, explaining what items belong in the red bin and how it fits into China's massive push for environmental protection.

• Pinyin (with tone marks): yǒuhài lājī
• Part of Speech: Noun
• HSK Level: N/A
• Concise Definition: Hazardous waste; harmful trash, specifically one of the four official categories in China's municipal waste sorting system.
• In a Nutshell: `有害垃圾` refers to any trash that contains harmful substances which could pose a threat to human health or the natural environment. Think of items that you know shouldn't go into a landfill: old batteries, expired medicines, fluorescent light bulbs, pesticides, and paint. In modern China, correctly identifying and separating `有害垃圾` is not just good practice—it's a legal requirement in many cities, complete with designated collection times and potential fines.

• 有 (yǒu): To have, to possess, there is. This is one of the most common characters in Chinese.
• 害 (hài): Harm, damage, injury, to cause harm.
• 垃 (lā): A character almost exclusively used in the word for “trash.”
• 圾 (jī): Like 垃, this character's primary use is in forming the word for “trash.”

The word is a straightforward combination of two distinct parts. `有害 (yǒuhài)` is a common adjective meaning “harmful” (literally “to have harm”). `垃圾 (lājī)` is the standard word for “trash” or “garbage.” Put them together, and you get `有害垃圾 (yǒuhài lājī)`, which literally translates to “harmful trash,” a perfect description for hazardous waste.

The term `有害垃圾` rocketed from relative obscurity to a household phrase following the 2019 implementation of mandatory waste sorting in Shanghai, a policy which has since been rolled out to other major cities across China. This initiative marks a significant turning point in China's approach to environmentalism, moving from a focus on industrial pollution to managing consumer waste at the individual level. Unlike in many Western countries where hazardous waste disposal is often a periodic, specialized event (e.g., a “hazardous waste drop-off day” at a local facility), in urban China, it has become a daily civic duty. Apartment complexes have designated times and supervised areas for residents to dispose of their sorted trash. An `阿姨 (āyí)` or volunteer will often watch to ensure you're sorting correctly. This reflects a broader societal value: a top-down, collective approach to solving national problems. The government sets a clear, ambitious goal (waste reduction and environmental protection), and the entire population is mobilized to achieve it. The sudden, widespread enforcement created a shared cultural moment, spawning countless memes, songs, and mobile apps designed to help citizens figure out if their leftover crayfish shells were `湿垃圾 (shī lājī)` (wet waste) or if a broken lightbulb was `有害垃圾`. For a learner, understanding this term isn't just about vocabulary; it's about understanding a key aspect of modern urban life and civic responsibility in China.

`有害垃圾` is a term you will encounter daily, primarily in the context of waste disposal.

• On Bins: You will see the characters 有害垃圾 printed on specific trash cans, which are almost always colored red.
• In Conversation: People use it when asking for help sorting their trash or discussing the new regulations. For example, you might ask a neighbor, “Is this battery considered `有害垃圾`?”
• Public Announcements: Public service announcements on TV, in subways, and in residential compounds constantly remind people of the four categories, with `有害垃圾` always being one of them.
• Formality: The term is official and formal, but because the context is an everyday chore, it's used by everyone in all levels of society without sounding stiff or overly academic. It's simply the correct, necessary term.

• Confusing with Recyclables: The most common mistake is confusing `有害垃圾` with `可回收物 (kě huíshōu wù)` (recyclable waste). While a glass bottle is recyclable, a broken fluorescent light bulb (made of glass) is hazardous because of the chemicals inside. A rechargeable battery might be considered hazardous, while a simple cardboard box is recyclable. The key distinction is potential harm, not material type.
• Not Everything Electronic is Hazardous: While old electronics often contain hazardous components (like batteries), the item itself might be classified differently depending on local rules. A large appliance might be considered a special recyclable, while only its battery needs to go into the `有害垃圾` bin.
• Underestimating the Importance: A foreigner might casually toss a battery into the wrong bin, thinking it's no big deal. In a city like Shanghai or Beijing, this can lead to a real, albeit small, fine (`罚款 fákuǎn`) or a public scolding from a neighborhood volunteer, which can be quite embarrassing. The rules are taken very seriously.

Understanding `有害垃圾` requires knowing the other three categories it is sorted with.

• 湿垃圾 (shī lājī): Wet Waste / Kitchen Waste. This category is for compostable, organic waste like food scraps, peels, and leftovers. This is often the most confusing category for Westerners.
• 干垃圾 (gān lājī): Dry Waste / Residual Waste. This is for anything that doesn't fit into the other three categories, like dirt, ceramics, disposable diapers, and cigarette butts.
• 可回收物 (kě huíshōu wù): Recyclable Waste. This includes paper, plastic, glass, metal, and clean fabrics.
• 垃圾分类 (lājī fēnlèi): Waste Sorting / Garbage Classification. The overall policy and action of sorting trash into different categories.
• 环保 (huánbǎo): Environmental Protection. The broader concept driving the `垃圾分类` initiative.
• 电池 (diànchí): Battery. The quintessential example of `有害垃圾`.
• 过期药品 (guòqī yàopǐn): Expired Medicine. Another classic example that must be disposed of as `有害垃圾`.
• 垃圾桶 (lājītǒng): Trash Bin / Garbage Can. You will look for the red one for `有害垃圾`.
